Data loading without needing a server API endpoint

[mkArtakMSFT]

With .NET running on both ends of the wire in a Blazor app, we have the opportunity to dramatically simplify data access with a strongly typed programming model. This issue tracks exploring adding a streamlined programming model for loading and manipulating data from the client.

I am very interested in this. I have created a pattern that lets me do this constrained by the current APIs. I made a video about it here. https://www.youtube.com/watch?v=PsmXZnvWfIo

yes the hole idea of blazor server is we can code the backend and frontend in one single project without need to create backend with webapi and then make request from blazor server to webapi , blazor server is solved that problem . but in .net 8 we have the auto render mode which is not actually make benefit for me because this mode require to use webapi .
so i'm stick with blazor interactive server,
but we can make blazor more more powerful, if we can have one blazor project that we can code backend and we can use Auto render mode with it,
To achieve this there is a suggestion in my mind:
1- every method in . razor will be shared for wasm (client), and interactive server mode.
2-if any method have [ServerOnly] attribute in . razor it will be in server only and to get access to this method from wasm(client) we need generate this method as endpoint and get access to it (this can achieve by webapi or signalr) if you guys choose signalR then make the signalR if its lost the cirecit then create new one automatically without need to refresh the website (because its for endpoints only and will not effect the state of blazor).
I hope something similar to this will be done in
.net 9.
